Check Digit Verification of cas no
The CAS Registry Mumber 52881-96-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,8 and 1 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 52881-96:
(7*5)+(6*2)+(5*8)+(4*8)+(3*1)+(2*9)+(1*6)=146
146 % 10 = 6
So 52881-96-6 is a valid CAS Registry Number.

Palladium-Catalyzed Decarbonylation of Amino Acid Derivatives via C-C Bond and C-N Bond Dual Activations

A unique decarbonylation of an amino acid derivative catalytic system has been established via palladium-catalyzed C-C bond and C-N bond dual activations. By employing 8-aminoquinoline as the directing group, this transformation has been found to facilitate the high chemoselectivity to decarbonylation of amino acid derivatives rather than intramolecular deamination or cross-dehydrogenative coupling reactions. This method provides a straightforward avenue for constructing diverse functionalized amide compounds in good to excellent yields. We proposed a possible reaction pathway that may go through the C-C bond and C-N bond dual activations on the basis of the mechanistic studies.
